How do you do that?

A buddy of mine (who was crashing at my place a long time ago) and is a computer nut once used my pocket AM radio (while I was out at work) to trace a break in the phone wire tacked to the wall.

I don't know how he found the broken wire. He was a bit schizo (in the true sense of the word) so I never got him to focus on it long enough for him to tell me....
